Metal Pall Ring Product Description

The Metal Pall Ring is a classic high-performance random packing, developed as a direct improvement over the metal Raschig ring. Its cylindrical body is punched with two rows of windows and bent inward to form multiple internal tongues. This structure greatly increases the open area, improves gas-liquid contact, and reduces pressure drop compared to earlier ring designs. Manufactured from 304, 316L stainless steel, or carbon steel, the Metal Pall Ring offers excellent mechanical strength, thermal stability, and corrosion resistance, making it suitable for a wide range of industrial mass transfer applications—from vacuum distillation to high-pressure absorption.

Product Highlights

• High Mechanical Strength: Metal construction provides far greater crush resistance than ceramic or plastic packings, preventing breakage during transportation, loading, and operation.
• Large Voidage & Low Pressure Drop: The open window and tongue structure significantly increases void fraction (up to 95%), reducing gas flow resistance and energy consumption.
• Excellent Gas-Liquid Distribution: Internal tongues guide liquid to the ring interior, creating uniform wetting and preventing channeling, which enhances mass transfer efficiency.
• Wide Temperature & Pressure Range: Suitable for both vacuum and high-pressure systems, with operating temperatures up to 450°C for stainless steel grades.
• Superior Corrosion Resistance: Available in 304, 316L, and other alloys to withstand aggressive chemicals, chlorides, and sour gas environments.
• Proven & Economical: As the industry standard metal random packing, it offers a balanced combination of performance, availability, and cost-effectiveness.
